Ben Cohen, a leading expert on SystemVerilog Assertions (SVA), wrote an article about Concurrent Assertions and their limitations when it comes to using delays inside SVAs. He also shows how to replace complex assertions with tasks. In the end, he points it out nicely: “implementing an assertion with tasks is acceptable; SVA is just a […]

C++ Implementation of Functional Coverage for SystemC

We release Functional Coverage for SystemC (FC4SC) library which provides mechanisms for functional coverage definition, collection and reporting. FC4SC is a header-only, C++2011-based library, that can be integrated with C++ applications, including SystemC models. It’s primary use case is to measure the level of exercise of SystemC models, basically to measure how many of model’s […]

How To: Alternative Ways to Implement Bitwise Coverage

In a previous post, Stefan provided implementations for several bitwise coverage patterns. In this post I will show an alternative way of implementing a couple of them, avoiding the usage of loops to iterate through all bits. Walking 1 and Walking 0 Coverage covergroup walking1_cg with function sample(bit [WIDTH-1:0] x); walking1_cp: coverpoint ($clog2(x) iff ($onehot(x)) […]

CoverageLens 2.0 Release

Coverage Lens (CL) is a C++ utility that checks if a specified set of RTL code coverage items (e.g. statement, condition etc.) is covered by querying an UCIS compliant coverage database. The main functionality is described in the How To Automate Code Coverage analysis with Coverage Lens article. CoverageLens 2.0 release includes support for functional […]
